Bears that mark more trees more successful in mating

Brown bears that rub against trees more often tend to have more offspring and more mates

Bears that mark more trees more successful in matingBrown bears that are more inclined to grate and rub against trees have more offspring and more mates, according to a University of Alberta study. The results suggest there might be a fitness component to the poorly understood behaviour. “As far as we know, all bears do this dance, rubbing their back up against the…

Innovative livestock grazing approach could reduce greenhouse gases

Innovative livestock grazing approach could reduce greenhouse gasesAn innovative approach to livestock grazing could help eliminate climate change-causing greenhouse gases, according to a new study. The research shows that a strategy called adaptive multi-paddock (AMP) grazing extracts methane gas from the atmosphere, locking it inside the soil through microbial activity. Methane gas has a climate warming effect that is 28 times more potent…

Cougars respond to roads based on traffic, topography, time of day

New U of A research outlines factors that lead cougars to select habitats near roadways in Alberta

Cougars respond to roads based on traffic, topography, time of dayA study by University of Alberta biologists identifies three key factors for how cougars select habitats near roadways: traffic, topography and daylight. “Cougars will avoid roads if there is human activity or while there is daylight,” explained Mark Boyce, professor in the Department of Biological Sciences and Alberta Conservation Association chair in Fisheries and Wildlife. “However, cougars will select habitat near…
